Abstract:The T3 tower of Dongguan International Trade Center is featured by complex elevation. Considering the comfort control due to wind vibration and coordination of structural members, architecture elevation and facade, it adopts structural system of exterior framed tube and core wall. From the bottom up, the exterior framed tube system respectively adopts structural systems of frame with large column-space, regular close-column tube and staggered close-column tube. Structural system of the tower was introduced. The overall principle and seismic performance objectives were set for performance-based design of structural members. Detailed finite element analyses were carried out for force transferring routes of some special parts, and treatment measures were provided.

Keywords:exterior framed tube; strut and tie method; super-short beam; performance-based design; cantilever wall; staggered column
